The 10-day ETHDenver 2022 came to an end. More than 170 teams of hackathon participants competed for the top 30 prizes totaling $1 million in bounties and prizes, $2 million in investment capital, and an additional 1 million SPORK matching pool.
Among the 30 winning projects, five of them are Infrastructure&Scalability projects, including Deus Ex Securitas, which uses machine learning to automatically audit smart contracts., Death Star, Hack and Scam Prevention with a MEV Frontrunne, Blocksnap, an On-chain Data Snapshots Made Easy, and etc. Six of them are DeFi projects, including SlowSwap, an MEV-resistant of Uniswap V2, and DustSweeper, which converts small tokens into ETH. Two of the DeFi projects are for NFT assets, which are Bunker.finance, a lending protocol backed by NFT collateral, and Mimicry Protocol, a derivatives protocol for NFT. There are also 5 Gaming&Metaverse projects and 4 DAO&Community projects.
In terms of networks building, nearly 20 projects will be built on multiple chains, the vast majority of which will be built on ETH or Polygon, with a few projects on Polka, BSC, Harmony, Algorand, Gnosis Chain, Metis, Arbitrum
Infrastructure&Scalability
Deus Ex Securitas：Using machine learning to automatically audit smart contracts
NLP models can classify solidity scripts by their vulnerability and could even point out what lines contribute to the vulnerable nature of the code.
Death Star
Death Star takes advantage of MEV to detect malicious transactions and fail them by outbidding them with an emergency transfer.
Users whitelist addresses in their approved "address book." When a token transaction to a non-whitelisted address occurs,the MEV frontrunner immediately sends a transaction that transfers all of a users' assets to a fallback address, with 2 times the gas of the detected transaction. This makes sure that the miner chooses your transaction before the malicious one.
Cannon：A Hardhat plug-in for declaring on-chain dependencies and enabling multi-chain development
Cannon is a Hardhat plug-in that allows you to configure your protocol's scripts, keepers, and on-chain dependencies for automated provisioning and deployment. Inspired by Docker and Terraform, Cannon comes with a built-in decentralized package manager (backed on Ethereum and IPFS) so users can easily share and download automations for existing protocols. With Cannon, validating frontends, constructing prototypes, and developing integrated protocols is easier than ever.
Blocksnap：On-chain Data Snapshots Tool
Blocksnap is a simple, powerful tool that makes it easy to capture snapshots of on-chain data, and utilize that data in your web3 application.
Blocksnap currently supports ETH Mainnet, Polygon, Arbitrum and Optimism (but this approach works with any EVM compatible chain).
IdentDeFi：A decentralized & open standard for on-chain compliance that utilizes ZK proofs to retain user anonymity
IdentDeFi is a decentralized and open standard that allows DeFi primitives to recognize compliant users.
Users undergo KYC once, and upon verification are minted a non-transferrable NFT. Protocols can then check if a user carries a KYC NFT, allowing them to trade any permissioned or permissionless market.
Defi
SlowSwap：prevents MEV front-running and sandwiching issues
SlowSwap is an AMM with a Verifiable Delay Function (VDF) that prevents MEV front-running and sandwiching issues. This project was implemented during the EthDenver 2022 Hackathon.
DustSweeper：Clean small token balances from your wallet and swap for ETH
DustSweeper allows users to swap small balance tokens for ETH without expensive gas transactions. Users just have to approve the tokens they’d like to sell, and “market taker” bots execute the swap.
DustSweeper is looking for crowdfund on Mirror currently, they’ve received 115 ETH，which is way beyond the original target: 50 ETH.Crowdfund contributors will receive 34% ownership of the DAO at launch (with 33% to the DUST treasury and 33% to liquidity incentives).
Bunker.finance：NFT-backed lending protocol offering instant liquidity via pooling
Bunker.finance is a decentralized protocol for NFT-backed loans. We use Compound’s pooling mechanism to facilitate instant borrowing and lending, removing the need for borrowers and lenders to wait to be matched with a counterparty. As a result, we are able to offer a superior UX to both borrowers and lenders.
Bunker.finance plan on integrating with Rarible's NFT indexer service to display NFTs in the modal which displays the user's NFTs available to deposit, once Rarible finishes adding support for CryptoPunks, which are the first kind of collateral we will support.
Mimicry Protocol：Defi derivatives protocol for NFT collections
Mimicry Protocol went far down that road of forking Synthetix but ultimately decided to leverage our own custom contracts and Scaffold-Eth instead. As a result our demo didn't fully implement the global debt pool, yield farming, and oracles that we had planned.
Nonetheless, they completed the following features:
- Connecting to Polygon via Metamask
- Deposit ERC-20 collateral and mint an ERC-721 to mark the position
- Collection appraisal middleware
- POC visualization of collateralized position data
- Burn ERC-721 to release collateral
ExchangeIt: Decentralized mobile marketplace
ExhangeIt is a decentralized mobile marketplace for individuals to create listings and submit offers for local goods around their location. Transactions are enforced by smart contract escrowing and completed using a GPS backed Chainlink EA. Disputes and bad actors are regulated by a DAO governance.
The main mechanisms for incentivizing people to meet and fully commit to their exchange obligations are based on two key functionalities:
1 Escrow for over collateralizing by enforcing a fixed deposit on both sides and a reward system;
2 Two-man rule for unlocking the escrow to retrieve deposit We've deployed a fully functional version of our mobile app on the Mumbai Testnet.
Skew You：Defi Vault to automate skew farming with risk mitigation for perpetual pools
Users can deposit funds into a vault that will automatically allocate their funds to highest earning skew arbitrage positions. We will use long and short positions, with leverage for increased capital efficiency. V1 uses Tracer Perpetual Pool tokens on Balancer and perpetual futures on GMX.
NFT
Supercool：A no-code NFT creation tool and tokenized social engagement engine
People can come to the Supercool on-chain drawing app and draw pixel art. They can either create pixel art from scratch or they can start off with templates. After drawing, people can mint their creation and share it on Twitter. The supercool engagement engine extracts Twitter engagement data like Retweets, Likes, and Comments and rewards drawings with the Supercool Social Token (SST) proportional to their engagement on Twitter. The Supercool Leaderboard pulls and displays this engagement data creating a gamified and fun NFT creation experience for users and shows you the most popular drawings. With the Supercool engagement engine, any NFT project can gamify social media engagement and strengthen their community in a fun way.
Gaming&Metaverse
Arena-Verse：The metaverse for athletics
Arena-Verse Create a metaverse for athletics that restructures the economics empowering the players.
- Create arenas and facilities for athletes in metaverse
- Structure governance with web3 tools
- Create insurance and financial products for athletes
ZK-Battleship：CryptoZombies for All Things Zero Knowledge
A on-chain battleship game using circom + snarkjs. If we had enough time the entire game would be played over p2p connection and the entire game would be rolled up into one transaction. Once we have completely built this product, we want to entirely document how to reconstruct it from scratch to do the same thing for zero knowledge that cryptozombies did for nft's. Game is not yet playable if you are here before code freeze
MoonScape：Multiplayer Web3 ARPG built with Unreal Engine
MoonScape is a simple, Unreal-based Web3 based ARPG deployed in-broswer via a React web app, with realtime multiplayer and network replication.
This project augments Unreal Engine with web3 functionality such as wallet-based login and user management, as well as programmatic NFT minting and trading triggered via in-game events and actions.
Funbug：P2E engine
Funbugᵍᵐ is an abstract P2E engine, decentralized and ready for any developer of a small game to implement and turn the game over to the community.
Space&the New Frontier
ZKmaps：Protecting user's location with ZK proofs
ZKmaps enables users to prove their location within a bounding area, GEOfencing, without disclosing thier excat location using ZK snarks.
In this case validating - (with a contract generated with circom) that the user was in ETHDenver within a specific time range (using theGragh). More specifically, this Proof-Of-Location-Protocol can be used for validating for POAPS DAOS for programatic funds dispersion, proving privately a location within a state or a city. Car hailing, location proximity matching, gaming and minting NFTS based on location and many more creative uses and utilities.
zkProof of Buffiness（zkPoB）：NFT Proof Tool
zkPoB is a mobile compatible tool that lets anyone prove they own a Bufficorn (or any NFT) without revealing what Buffi they own or the address they are verifying themselves with.
Fracture | Constitute：Document Recovery via Trusted Social Consensus
The UNHCR estimates that 84 million people are forcibly displaced globally. In many cases, it is unsafe to travel with any identification document, to ensure their protection when they finally arrive in a destination State, they are often registered by States or NGOs.
We want to provide an option for the forcibly displaced to recover their identity or any data that they may want to have from their home country without having to carry it on their journey.
22222.World：VIP Membership Through NFT Ownership
22222.World is an exclusive club of members. Each member purchases an NFT on Opensea. That NFT can then be easily verified using our website connected to any valid web3 wallet that contains the NFT. It allows for easy, decentralized sale and verification of NFT based VIP memberships.
Through Tableland integration small organizations are easily able to track attendance in a decentralized manner.
Wallet
Kiyomi：Multi-chain mobile wallet
With the latter in mind, Kiyomi presents the concept of the “mini app” inside the wallet. It is the ability to download mini-apps that suit the needs of the user, or that fit the needs of a particular blockchain ecosystem. In this context, in Kiyomi, a user may unlock mini apps or mini experiences based on the tokens held — for example, unlocking a mini-game for a particular NFT collection. The user may also download tools, in the form of a mini app, that allow the user to be more engage in a blockchain ecosystem — such as a governance mini-app for a DOTSAMA parachain.
The democracy mini-app allows users to view on-chain proposals, create proposals, second proposals, and vote for referendums directly from their wallet through the use of the democracy pre-compile.
DAOS&Communities
AcademyONE：An education platform for incentivize creation
AcademyONE is An education platform allowing projects to outsource and incentivize creation of high quality learning materials. A platform for educators to make money fulfilling bounties. A place to learn and earn governance rights in the process.
DoOrDon't：An evaluation of DAO
DoOrDon't supports new DAO joiners to evaluate the transparency and decentralization of a DAO. With the help of our trust scores, they will only join DAOs that align with their values.
Intuition：Theoretic Decentralized Identity System
Intuition is a peer-to-peer system for decentralized identity that is economically, reputationally, and “time”-collateralized, facilitating the construction of asymptotically probabilistic, non-deterministic peer-to-peer identity models. This system not only allows for new types of claims to be made, but also bolsters existing decentralized identity efforts through new efficiencies and “skin-in-the-game”.
Background Network：Decentralized Help Center as a service protocol
Background Network creates a help center with us (it is a web page). It is a forum like UI– similar to Stack Overflow. It can be whitelabled or hosted on our domain. (We can use Discourse) Users can sign in with their wallets and create a profile listing their communities to ask questions and answer questions. They don’t need to sign in to read the content. We can pre-populate the page with Q+A from their Discord help channel Community members are incentivized via tokens to ask relevant questions and share relevant answers.
Others
LOUDVRS
LOUDVERSE is a 2-sided marketplace for funding hard-to-quantify public goods like music, poetry, and theater. This project proposes an extension to Quadratic Funding to account for two key real-world economic constraints that apply to public goods projects:
Constraint on available funding pool
- Per-proposal minimum viable funding constraint
- The Pool Constraint is the overall amount of matching subsidy funding available for the given funding round. The goal is to use the available funds to fund the greatest possible amount of viable public.
Proof of Meditation
Proof of Meditation is an App to incentivize people to take more care of their health and emotional wellbeing through meditation. It can be used as DAO Tool.
How it works: users can decide on the first day of each month whether or not to join a 21-day meditation by choosing to meditate for 10 minutes each day and then staking tokens to bet on their goals, with a portion of the user's staking tokens locked into the pool for that meditation for each missed session. 21 days later, each participant will receive staking tokens, the number of which is related to the number of days clocked in, and the tokens in the pool will be distributed among users who have clocked in for 21 days.
Kudos：Rewards and Incentives for Farmers and Food System Supporters
Kudos has a food system made up of a complex network of farmland, farmers, farmers markets, logistics and distribution providers, co-operatives, distribution mechanisms, and other aligned parties.
A Guild can be defined as any group or individual who is able to make positive contributions to the Colorado foods system. A yet to be established DAO (in the works!) will provide Guilds with the ability to distribute kudos. Goals can be set for a wide range of environmental or social goals. Once goals are met, Guilds can distribute tokens to their contributors.
Colorado Aware: Moving Colorado To A Net Zero World One Notification At A Time
Colorado needs to make the transition to renewables as soon as possible. The 2040 goal set by Governor Polis is just the start. There is work to do technologically, culturally, and with regulations. A transition to renewables is a lot of work. Colorado Aware is an application to enable all of that. It is deliberately built as a change management approach to the renewable energy transition. It follows a strategic development that gradually moves users into a blockchain environment for distributed energy resource (DER) management and optimization.
Colorado Aware, with a true MVP beginning, will help optimize the onboarding of renewables to the grid, to our households and empower future innovation in energy (like tokenized conservation incentives, or peer to peer energy trading). This is just the beginning for Coloradans' to become Aware of their impact and partake in the state's transition to renewable energy.
